| 摘 要： | 建议了一种基于改进的灰色关联度进行结构损伤识别的方法。该方法弥补了传统关联度的一些不足,并能较准确、快捷、简便地得到损伤结构的动力响应参数与完好结构对应参数之间的关联度,通过对关联度分析,可以方便地识别结构是否出现损伤,并能定性地给出损伤程度的大小。示例分析表明,利用本文建议方法的计算结果更符合实际。

| Abstract: | A new method for the structural damage recognition is proposed based on an improved gray correlation analysis.Some insufficiencies of the conventional gray correlation analysis method are remedied in this method and the Correlation of dynamic response parameters is obtained more accurately and quickly.Through the correlation analysis,the new method can easily identify whether the structure appears to be damage,and can also give the degree of damage qualitatively.By example analysis,It is shown that the calculating results by the proposed method are in better agreement with reality. |
